Hi, Spring fans! Welcome to another awesome (and oh-so-agentic) week in Spring! We've got a ton to look into, and I've got even more to prepare for next week's DevNexus event in Atlanta, GA, so let's dive right into it! (Be sure to say "hi" if you're going to be there, though!)

• You've heard of Agent Skills before, right? The new thing announced about a month ago by Anthropic as a way to conditionally add knowledge about your expectations for workflows, processes, conventions, etc.? Well, good news! In this video, DaShaun Carter, James Ward, and I look at the amazing support for building Agent Skills (.md) with Spring AI and--- you heard it here first! ---the new SkillsJars project!
• In this video, I look at some of my favorite features in the new Spring gRPC 1.0 release, going from .proto…

Hi, Spring fans! In this installment I talk to the amazing Glenn Renfro about Spring Batch, Spring Integration, Spring AI, and much more — plus why you should definitely register to attend the amazing Devnexus event in Atlanta, GA!

Hi, Spring fans! Welcome to another rip-roaring installment of This Week in Spring! It's Lunar New Year or Chinese New Year for billions of people around the world and to those who celebrate, Happy Chinese/Lunar New Year (新年快乐)! Or Happy Spring Festival (春节快乐)! (My favorite kind of festival!)

In honor of the auspicious day, I asked the AI to generate an image of the fire horse, and it did not disappoint!

Awesome!

You know what else is awesome? So much amazing content from the community this week, so let's dive right into it!

• Nice! An article on using Spring AI on Baeldung.
• This is awesome! A micro-optimization discovered in OpenJDK that, for some (admittedly uncommon) use cases, results in 400x performance improvements.
• Speaking of performance! Did you see this MCP server performance benchmark? Spring AI crushed it! Our performance and transactions-per-second numbers were the best among similar implementations in Python…

Hi, Spring fans! I've been waiting for this episode for so long! Today, we're finally joined by my friend Richard Fichtner, who so took pity on my plight waiting for music to be added to the GraalVM that his company, XDev Software, created the music-maven-plugin, the best Maven plugin, ever! This episode was recorded live at the amazing JFokus 2026 event!

Hi, Spring fans! Welcome to another installment of This Week in Spring! It's February 10th, 2026, as I write this from lovely London, UK. I spoke at the local Java User Group here last night, had a wonderful time. Tomorrow, I'm going home. It's been fun, but it's time to conclude this roller coaster whirlwind tour of Toronto, Canada; Helsinki, Finland; Stockholm, Sweden; Istanbul, Turkey; and London, UK.

I've been busy, but as usual, the community's been busier! There's a ton to get into so let's dive right into it!

• I did a video on how to build production-worthy AI systems and services with Spring AI. In it we look at most of what you need to know from Spring AI and we look at how to make it production worthy with observability, scalability, and - very importantly - security. Yes, security! We look at the new experimental Spring AI Community project called MCP Security which we can use to, you guessed it, secure MCP endpoints (in this case, with OAuth).
• another very interesting effort from our pal Thomas Vitale. It's called Docling, and it's a tool to prepare documents for AI (using Spring AI, natch)
• why AI feel hard …

hi, Spring fans! In this installment I have the privilege of talking to JetBrains legend Marco Behler

Hi, Spring fans! This week I'm in northern Europe. I went on the Vaadin cruise from Finland to Sweden, gave a talk on a boat, then arrived in Stockholm in time for the amazing JFokus 2026 event where I had the privilege yesterday of doing a deep dive with my pal James Ward on Spring AI and agentic patterns (some of which we also look at in this very roundup). Later today, I'm doing a talk introducing the new Spring Boot 4 support. Busy day, so let's dive right into this roundup!
